State of New Jersey, have invented a neW' and Improved Clean-Out, ofwhich the following is a full, clear, and exact description.

The invention relates to sanitary apparatus such as water closets,sinks, urinals, traps and the like. 7 I

The object of the invention is to provide a new and improved clean-outor manhole for apparatus such as described, and arranged to prevent theescape of foul odors or noxious gases or liquids by way of the cleanoutinto the room in which the apparatus is located.

In order to accomplish the desired result, use is made of a water jacketsurrounding the clean-out opening and open to the inner face of thecover, the said water jacket being connected with a water supply andhaving an outlet leading into the bowl or other part of the apparatus.

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of thisspecification, in whichsimilar characters of reference indicate corresponding parts in all 'theviews.

Figure 1 is a sectional side elevation ofthe clean-out shown applied tothe bowl of a water closet, the section being on the 11116 1-1 of Fig.2;

Fig. 2 is a face view of the same with the cover removed and the inletand outlet chambers shown in section; and

Fig. 3 is a face view of the inner end of tha, manhole.-

The improved clean-out is shown applied to the bowl 10 of a water closetand which bowl is provided with the usual flushing rim 11 and the waterseal 12 at the outlet. In the wall portion 13 of the bowl at the waterseal 12 is arranged an opening 14 through which access is had to theinterior of the water seal for repairs or other purposes, and the outerend of this opening 14 is normally closed by a cover 15.

In order to prevent any }gases or liquids from leaking past the jointsetween the face of the wall 13 and the cover 15, use is made of a waterseal in the form of an annular water jacket 16 formed in the wall 13and.

.surrounding the opening 14. The water jacket 16 is open to the innerface of the cover 15- and is connected near the top the water jacket 16is CLEAN-OUT.

a water inlet chamber 18 formed in the wall of the bowl and opening atits upper end into the flushing rim 11 so that water assing throu h thelatter can pass into the c amber 18 and from the latter by way of theport 17 into the water jacket 16 to fill the same. The upper portion ofconnected by an outlet port 20 with an outlet chamber 21 formed in thewall of the bowl'adjacent the chamber 18, as plainly indicated in Fig.2. The outlet -chamber 21'is provided with a .port 22 opening into thebowl 10 a distance below the flushing rim 11 so that the water passinginto the water jacket 16 can circulate through the same and ass outthrough the ort 20 into the cham er 21 and from'the atter by way of theport 22 into the bowl 10. Thus by the arrangement described fresh wateris circulated throu h the water jacket 16 every time the bowl is flushedby water from the rim 11.

The inner face of the cover 15 is provided by a port 17 with with anannular rib 25 which projects centrally into the water jacket 16 toallow the water to circulate around the rib thus providing a largesealing surface to prevent the escape of gases and liquid by way of thejoint between the cover 15 and the outer face of the wall 13. A gasket26 of ruib ber or other suitable material is interposed between thejoint of the cover 15 and the outer'face of the wall 13, and the innerface of the cover 15,is provided with short annular ribs 27 located onoppreferably posite sides of the ribs 25 and. serving to press thegasket 26 into annular recesses 28 formed in the outer face of the wall13.

In order to fasten the cover 15 in position use is preferably'made of ascrew 30 which screws in the shank or hub 31 of an arm 32 adapted topass through grooves 33 formed in the wall of the opening 14 andextending from the outer end of the opening to the inner end thereof.The ends of the arm 32 are adapted to be passed into grooves 34 formedin thewall of the opening 14 at a right angle to the grooves 33 so thatafter. the arm 32 has been passed inward in the grooves 33 and is thenturned to engage the grooves 34 then the arm is is provided whichsurrounds the opening 14 and is open to the inner face of the cover- 15to prevent the escape of obnoxious odors, gases, or liquids from theoutlet end of the bowl of the water closet.

It will also be noticed that the manhole cover 15 can be securelyfastened in position or readily removed whenever it is desired to do sofor cleaning out purposes.- As fresh air is circulated through the Waterjacket at each flushing operation of the bowl it is evident thatsediment and the like is not liableto accumulate in the water jacket andthe latter is keptfclean and sweet.

Having thus described'my invention, I

. claim as new and desire to secure by Let- Y ters Patent 2- A clean-outfor water closet bowls having an opening in the wallof the bowl at thewater seal thereof, a cover closing the said opening, an annular water'acket formed in the said wall and surroun ing the wall of the saidopening, the water jacket being open to the inner face of the saidcover, a water inlet chamber formed in the said wall above the waterjacket, the upper end of the said inlet chanrber connecting with theflush. ing rim of the bowl, a port connecting the bottom of the saidwater inlet chamber with the top of the said Water jacket, an outletchamber formed in the said wall adjacent the said inlet chamber, a portconnecting the top of the said water jacket with the bottom of the saidoutlet chamber, and a port connecting the said outlet chamber with theinterior of the bowl and located above the port connecting the outletchamber and the water jacket.
